Field Guide

Of the three species of catalpas in our state, northern catalpa is the only one native to Missouri (specifically, the Bootheel region). It has been planted widely, though, and has naturalized in many places. A popular ornamental and shade tree with pretty, orchidlike flowers and long, beanlike fruit.

Gray dogwood is a deciduous, thicket-forming shrub. Its small, creamy-white flowers occur in branched clusters, and its white or pale blue fruits are supported by red stalks — a characteristic that makes it attractive for ornamental uses.

Rough-leaved dogwood is one of Missouri's hardiest shrubs, capable of withstanding cold and drought. The leaves of this thicket-forming species emit a faint odor of sour milk.

Black locust, a member of the bean family, is easy to appreciate in May and June, when its showy white clusters of flowers perfume the breeze with their sweet smell. Bees like the flowers, too.

There’s no mistaking Kentucky coffee tree when its large, tough seedpods are hanging from its limbs or dropping to the ground below. Unpopular as food with today’s wildlife, these seedpods might have fed mastodons and other large, extinct North American mammals.

Pin oak is one of the easiest trees to recognize by its shape alone: It has a tall, straight trunk, an overall pyramidal or conical shape and, most notably, the branches on the lower third of the tree angle downward.

Limber honeysuckle is a native Missourian. It's uncommon and widely scattered in the state, but it does well as a trellis vine. Identify it by its crowded clusters of tubular, yellow or greenish-yellow flowers, tinged with red, purple, or pink, that are noticeably enlarged on one side at the base.

One of Missouri's beautiful native honeysuckles, grape honeysuckle is found mainly in the northern two-thirds of the state. In the native plant garden, it is easy to grow, but it is not aggressive like the introduced invasive Japanese honeysuckle.
